An Investigational Scan (64Cu-Labeled M5A Antibody) in Combination With SOC Chemotherapy and Radiotherapy in Locally Advanced Rectal Cancer

Locally Advanced Rectal Carcinoma Clinical Trial

Official title:
Pilot Study: Imaging Tumor Extent and Response Before and After Neoadjuvant Chemotherapy and Radiotherapy in Locally Advanced Rectal Cancer Using 64Cu-Labeled M5A Antibody to Carcinoembryonic Antigen (CEA)

Clinical Trial Summary

This early phase I trial investigates how well 64Cu-labeled M5A antibody scan works in assessing tumor activity before and after patients with rectal cancer that has spread to nearby tissue or lymph nodes (locally advanced) who are undergoing chemotherapy and radiotherapy. Using 64Cu-labeled M5A positron emission tomography imaging may play a significant role in imaging patients with colorectal cancer.

Clinical Trial Description

PRIMARY OBJECTIVE: I. To determine if the Copper Cu 64 anti-carcinoembryonic antigen (CEA) monoclonal antibody M5A (64Cu labeled M5A antibody) demonstrates a potentially impactful finding for patient management either in the pre-treatment scan (potentially impacting choice of therapy or impacting the radiotherapy [RT] plan) or the scan immediately prior to planned surgery (after standard care [SOC] chemoradiation) in patients with locally advanced rectal cancer. SECONDARY OBJECTIVES: I. To determine the safety of administration of 64Cu labeled M5A antibody. II. To describe/summarize each of the 15 patients' 64Cu-M5A positron emission tomography (PET) imaging findings and corresponding SOC scans and pathology. OUTLINE: Patients receive 64Cu labeled M5A antibody intravenously (IV) over 5 minutes on day 0 pre standard of care chemo/radiotherapy and on day 0 post chemo/radiotherapy. Patients also undergo 64Cu-M5A PET scan on day 1 pre chemo/radiotherapy and on day 1 post chemo/radiotherapy. After completion of the study treatment, patients medical records are reviewed up to 2-3 months. ;
